Versuchsvorschrift

A mixture of 2-bromodibenzo[b,d]thiophene (3.22 g, 12.24 mmol), 9-phenyl-9H-9′H-3,3′-bicarbazole (2.5 g, 6.12 mmol), and sodium t-butoxide (1.764 g, 18.36 mmol) in 100 mL of xylene was bubbled with N2 for 20 min. Pd2(dba)3 (0.056 g, 0.061 mmol) and dicyclohexyl(2′,6′-dimethoxybiphenyl-2-yl)phosphine (0.100 g, 0.245 mmol) were then added, and mixture was then bubbled with nitrogen for another 20 min. The reaction mixture was refluxed under N2 for 24 h. The mixture was cooled and filtered through Celite. After solvent evaporation, the residue was coated on Celite and purified by column chromatography using up to 50% dichloromethane in hexane as solvent. 9-(dibenzo[b,d]thiophen-2-yl)-9′-phenyl-9H,9′H-3,3′-bicarbazole (2.1 g, 3.55 mmol, 58.1% yield) was obtained.
